LPC2132FBD64,151 datasheet by NXP Semiconductors

LPC2132FBD64,151 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency of the LPC2132FBD64,151?
  The maximum clock frequency of the LPC2132FBD64,151 is 60 MHz.
• How do I configure the oscillator for the LPC2132FBD64,151?
  The oscillator can be configured using the PLL0CFG and PLL1CFG registers. The PLL0CFG register is used to configure the PLL0, which is the main clock source, while the PLL1CFG register is used to configure the PLL1, which is used for the USB interface.
• What is the purpose of the VPB (VCC Pin Bypass) pin on the LPC2132FBD64,151?
  The VPB pin is used to bypass the internal voltage regulator and connect an external voltage source to the internal circuitry. This is useful when an external voltage regulator is used to power the microcontroller.
• How do I use the ADC on the LPC2132FBD64,151?
  The ADC on the LPC2132FBD64,151 is a 10-bit successive approximation ADC. It can be configured using the ADCR register, and the conversion result can be read from the ADGDR register.
• What is the purpose of the BOD (Brown-Out Detector) on the LPC2132FBD64,151?
  The BOD is used to detect when the voltage supply to the microcontroller drops below a certain threshold. When this happens, the BOD generates a reset signal to reset the microcontroller.
